Home Secretary Theresa May has responded to an urgent question from Labour in the House of Commons by saying there was no "big bang" solution to tackle delays in issuing passports. She said the government would take a "series of measures to address pinch points".
She said there was "no single solution" to address a backlog in applications.
Overseas applicants would also be offered a 12 month extension, alongside a free upgrade for urgent applicants, the Home Secretary said in a statement.
Operations will also be reviewed at the passport office, she added.
Shadow Home Secretary Yvette Cooper tabled the urgent question on passports and told the House of Commons the current situation was a "sorry shambles".
